LUND, Sweden (UPI) -- Dogs, like humans, are susceptible to contagious yawning, but it develops gradually and puppies younger than 7 months seem immune, Swedish researchers say.
Researchers at Lund University, writing in the journal Animal Cognition, report a developmental, age-related trend in susceptibility to contagious yawning seems to operate in both humans and dogs.
Previous research has demonstrated contagious yawning in humans, adult chimpanzees, baboons and dogs, and suggests it is evidence of empathy.
The researchers studied 35 dogs between 4 and 14 months of age in bouts of play and cuddling with humans and observed the dogs‘ responses when people repeatedly yawned, finding only dogs older than 7 months showed evidence of contagious yawning.
A similar pattern exists in humans, researchers said, with children typically beginning to yawn contagiously at age 4 when a number of cognitive abilities begin to show.
The results suggest a general developmental pattern, shared by humans and other animals, in terms of affective empathy and the ability to identify others’ emotions, they said.

개가 사람의 하품을 따라하는 이유?
최근 스웨덴의 연구원들에 따르면 사람처럼 개도 하품을 하면 따라하는 것으로 밝혀졌다. 다만 그런 인지 반응은 7개월을 넘어서 서서히 발달하는 것으로 조사됐다.
과거에 발표된 연구들에 따르면 하품을 따라하는 습성은 사람, 침팬지, 개코원숭이와 개에서 나타났는데 이는 그들도 공감할 수 있는 능력이 있다는 것을 보여준다.
스웨덴 연구팀은 4개월에서 14개월된 35마리의 개들을 대상으로 사람이 하품할 때 어떻게 반응하는지 관찰했다. 그 결과 7개월이 넘은 개만 하품을 따라하는 것으로 나타났다.
사람도 비슷한 경향을 보였다. 어린아이들은 4살 이후에 하품을 따라한다고 밝혀졌다.
